EYELETING-MACHINE.

Application filed June 28, 1910.

To all whom it may concern:

Be it known that 1, ROBERT B. SMITH, a citizen of the United States,residing at Stoughton, in the county of Norfolk and State ofMassachusetts, have invented certain Improvements in Eyeleting-Machines,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for setting fasteners, such, forexample, as eyelets and the like, and more particularly to machines forhandling and operating upon fasteners which are non-circular in shape.

It is frequently necessary to setfasteners which areelongated and,difiiculty has been experienced in handling these fasteners anddelivering them from the magazine to the raceway of an automaticmachine.

The general object of the invention is to provide a machine forsupplying and setting such elongated fasteners or fasteners having morethan one barrel, or single fasteners disposed with their barrels side byside.

The machine illustrated in the drawings is particularly adapted tohandle fasteners of the type known as twin eyelets. These fastenersgenerally consist of two barrels similar to those of ordinary eyeletsstruck out from a single elongated flange.

Heretofore it hasbeen customary to supply twin eyelets by hand to thesetting dies in which they were to be clenched. This was partly due tothe difficulties referred to above and partly to the fact that nosuitable means was known for supplying such eyelets from a raceway to aplurality of dies such as are necessary for effecting the setting of theeyelet.

An important feature of the present in vention consists in aconstruction whereby fasteners of the character described, or two singlefasteners at a time. maybe supplied from a raceway to a plurality ofsetting dies properly positioned to cooperate to set the fastenerdelivered thereto.

One preferred embodiment of the invention includes a structure having aplurality of setting dies and a corresponding phirality of upsettin'gdies, the said dies being arranged.- in pairs,- each pair consisting: of

setting die and a cooperating upsetting die. In the machine herein shownsuch pair comprising a setting die and an upsetting die is arranged infront of another similar pair and the raceway is positioned in line withthe setting dies at the rear thereof and may rec procate along the linementioned.

. The double barreled fasteners lying longitudinally in the raceway asheretofore described, the fastener at the foremost end of the racewaywill, when the raceway is brought forward, be presented to the dies withthe barrels in proper relation to the said dies to be operated uponthereby. A plurality of spindles mounted within the setting dies, onefor each barrel of the fastener, enter the fastener and remove it fromthe raceway as the latter is retracted.

WVhile I have illustrated a machine for handling twin or double barreledfasteners, it should be understood that my invention is notlimitedto'the handling of fasteners with two barrels but may be successfullyembodied. in machines which will handle fasteners with any desirednumber of barrels, which may be designated broadly as multiplefasteners.

The spindles heretofore referred to for entering the barrels of thefastener and removing the latter from the raceway are preferably mountedupon a common base actuated by a single actuating means, such as aspring. This insures that the spindle shall move simultaneously and thusshall onter the barrels of the fastener without difficulty.

Another feature of my invention comprises the provision, in a machinehaving a raceway for supplying or delivering fasteners, of improvedmeans for retaining the fasteners in the raceway until it is desired toremove one or more for insertion in the work. I preferabl effect thedesired result by means of a yielding spring'latch lying above theendmost fastener in the raceway and having its end turned downwardly soas normally to lie in front of said fastener. Such de ice will yield toallow the ready removal of one or more fasteners when desired andimmediately return to position to retain the remaining fasteners in theraceway.

Other features of the invention will appear more: hilly in the followingdescription alnd will be pointed out in the appended C lllTlS- In thedrawings.Figure 1 is a side cleva-tion. partly in section. of aneyeleting machine embodying the features of my invention: Fig. 2 is aperspective view of a twin eyelet of the type adapted to be handled andset by the illustrated machine: Fig. 8 is a detail, partly in section.showing the arrangement of the po ts in the magazine: Fig. 4 is a detailplan view of the forward end of the raceway: and Fig. 5 is a section onthe line 5-5 of Fig. 4;.

Referring to the drawings, 2 designates a base or suitable support uponwhich the frame 3 of the machine is mounted. The frame 3 is formed witha forwardly projecting upper portion 4 in the end of which are mountedthe upsetting dies 6 for upsetting or clenching the eyelet barrels onthe work.

6. 6 represent two upsetting dies mounted within the head 7 of a holder8. The said holder 8 is secured in a suitably formed a1 erture in theend of the frame 4 by means of a set screw 9 and is stationary duringthe operation of the machine.

A plunger 10 is mounted to reciprocate vertically in a guideway 11formed in the lower'part of the frame of the machine, the axis of thesaid plunger coinciding with that of the holder 8. The plunger 10 isbored out as shown at 12 to receive and hold rigidly a die holder 13 inwhich are mounted setting dies 14. 14. Each of the setting dies iscentrally drilled to allow the passage of a spindle 15. The die holder13 is also drilled in line with the holes drilled in the setting dies sothat the spindles 15 loosely pass through both the setting dies andtheir holder. The spindles 15 are both rigidly mounted at their lowerends in a button 16 which is freely slidable vertically within therecess 12 below the die holder 13. \Vithin said recess is also located aspring 17 which normally presses the button 16 and the spindles carriedthereby into their uppermost position, as shown in Fig. 1. The upsettingdie holder 8 is mounted so that the upsetting dies 6, 6 lie one in frontof the other, or, in other words. the said dies lie in a line extendingfrom the front toward the rear of the machine. The setting dies 14, 14are mounted to register respectively with their corresponding upsettingdies 6, 6 so that when a fastener, such as that illustrated in Fig. 2,is placed upon the lower or setting dies and the latter are moved towardthe upsetting dies 6, the said upsetting dies will upset or clench theends 19 of the barrels of the fastener 18.

The mechanism for imparting a reciproeating movement to the plunger 10is connected to the lower end thereof and may be of the same characterand construction as that illustrated in U. S. Letters Patent No.898,729, granted September 15, 1908, to J. F. Davey. V

In order to supply the fasteners 18 to the sets a magazine 20 forholding thefasteners and a raceway 21 for receiving them from themagazine and delivering them to the dies are provided. Within themagazine is an agitator 26 which oscillates and keeps the fastenersconstantly moving. The magazine and raceway aremounted to reciprocate inthe manner disclosed in the U. S. Patent above referred to. In order toeffect separation of eyelets or fasteners in the magazine and permittheir delivery therefrom to the raceway, ports 22 are provided in a potion of the periphery of the magazine. These ports are separated fromeach other by studs 23 which are cylindrical in form'and are so 7 spacedthat the fasteners 18 can only pass lengthwise therehetween one at atime and with the barrels of the fastener upward. By reason of thecylindrical formation of the studs 23 the fasteners, while passingbetween the studs, are free to turn either upwardly or downwardly tobring their longitudinal axis into alinement with their subsequentdirection of movement in the raceway 21. Any danger of blocking orchoking of the ports or of the raceway is thus eliminated and asufficient number of eyelets is delivered to the raceway to supply theneeds of the machine. An inspection of Fig. 3 will show that in passingthroughthe ports 22 of the magazine the eyelets can turn in eitherdirection. This facilitates their entrance into, and proper arrangementwithin, the raceway.

The raceway is inclined downwardly and forwardly as illustrated in Fig.1 and when in its delivering position intersects the axis of therearmost dies and terminates substantial-ly in line with the axis of theforemost dies. At the forward and lower end of the raceway a springlatch or detent 24 is mounted by-means of a screw 27, or other suitablesecuring means. The forward end of the latch is deflected toward thecenter of the raceway as shown in Fig. 4 so as to lie above the endmostfastener in the raceway. The tip of the latch 24 is turned downwardly asshown at 25, the downwardly turned portion lying in front of theforemost fastener in the raceway. as clearly illustrated in Fig. 5. Thelatch 24 normally retains the supply of eyelets in the raceway but willyield to allow the removal of an eyelet by the spindles 15 when desired,immediately moving back into position in front of the next precedingeyelet in the raceway.

By constructing the latch so that it shall lie above. and extend down infront of, the eyelet which it engages in the raceway. an importantadvantage is secured in handling eyelets having anelongated outline inasmuch as it is necessary that such eyelets be presented to the sets inproper angular position with relation thereto. The latches heretoforeused in automatic eyeleting machines engage the side of the eyelet andhave a tendency to rotate the same as it is taken from the raceway. Thisis immaterial when circular fasteners, such as round eyelets, are beingused but becomes a source of difficulty when an elongated or doublebarrele'd fastener is to be handled. lVith my improved device, the endsof the spindles 15 may, after passing through the barrels of thefastener, engage the latch and lift it slightly out of engagement withthe fastener so that there is no tendency whatever to rotate thefastener as it is taken from the raceway and it is therefore easy toposition the fastener properly and accurately upon the setting ies.

In the operation of the machine the agitator 26 keeps the fasteners inthe magazine in constant movement and a sufiicient number of them isdelivered through the ports 22 always to maintain a supply in theraceway. As the plunger 10 is moved upwardly, the spindles 15 enter thebarrels of the foremost eyelet in the raceway. The raceway is then movedrearwardly and the eyelet which is held upon the spindles 15 isdisengaged from the raceway, the latch 2-1 immediately dropping down infront of the next fastener and preventing its escape. The plungercontinues to move upwardly and the fastener carried by the setting dies14 mounted upon said plunger is inserted in the work and upset orclenched against the upsetting dies 6, the downwardly projectingportions of which depress the spindles 15 against the tension of thespring 17. In the return of the plunger to its lowermost position theraceway is again moved forwardly in order to bring another fastener intoposition to be received upon the spindles of the setting dies in thenext operation of the machine. It should be understood that the numberof setting dies 14 and of the corresponding upsetting dies 6 is notlimited to two but is only determined by the number of barrels 19 uponthe fastener to be handled by the machine.

Throughout this specification and in the following claims I use the termsetting die to refer to that die which receives the fastener from theraceway, and the term upsetting die to refer to the cooperating diewhich upsets or clenches the barrel of the fastener upon the work. Ialso use the term pair to define a setting die and its cooperatingupsetting die. For example, a setting die 14 and its cohperatingupsetting die 6 form a pair in the sense in which that term is to beunderstood. The line in which the raceway 21 reciprocates extends fromthe front toward the rear of the machine and is coincident with theplane containing the setting dies 14: and the upsetting dies 6, that isto say, the raceway is arranged to reciprocate in the direction of theline joining the dies 14 which receive the fastener from the raceway.

Having thus fully described my invention, what I claim as new and desireto secure bv Letters Patent of the United States is 1. A machine forsetting fasteners having, in combination, a plurality of setting dies, acorresponding plurality of oppositely disposed upsetting dies, and meansfor successively bringing fasteners into alinement with and between allthe dies, said means comprising a raceway movable to and from adelivering position in which it intersects the axis of one setting dieand terminates substantially in the axis of an adjacent die.
